What is painless DNA testing?

Most pregnant women wonder whether they need to do a painless DNA test during pregnancy. Pregnant women can have a certain understanding of the development of the fetus through painless DNA testing, and can also find out whether the fetus has other symptoms. So, what does the painless DNA test for pregnant women do?

One is that pregnant women undergo painless DNA testing, which is mainly used to check whether the fetus's sex chromosomes are abnormal, including repeated abnormalities, malformed segments, missing segments, inverted segments, etc., all of which are abnormalities in the chromosome structure. It is also necessary to check whether the chromosome number is abnormal. Nowadays, many babies with Down syndrome are born with one missing chromosome compared to healthy babies.

Second, if the examination finds that the fetus has congenital abnormalities in the chromosome structure and number, it will make the pregnant woman prone to repeated miscarriages, or even genetic diseases or infertility. Pregnant women can use DNA testing to find abnormalities in the fetus's sex chromosomes and then develop a treatment plan based on the fetus's condition.

Third, if the fetus has chromosomal abnormalities after birth, it may easily lead to sepsis or other serious tumor diseases. Doctors can understand the status of sex chromosomes and then carry out targeted treatment based on the baby's physical condition.

The minimally invasive DNA prenatal non-destructive testing technology mainly uses the venous blood of pregnant women, and then uses the new generation of DNA sequencing technology to sequence the mineralogic DNA fragments in the jugular vein blood of pregnant women. Then, the test results will be statistically analyzed to further determine the genetic material of the fetus and whether the fetus has certain sex chromosome disorders. This method can reduce the risk of giving birth to patients with chromosomal disorders.
